ISO 8191-1 Furniture - Assessment of the ignitability of upholstered furniture -Part 1:Ignition Source : smouldering cigarette
ISO 8191-1 Fire test to Upholstered Furiture - Standard Brief：
This part of ISO 8191 lays down a method of test to assess the ignitability of material combinations, such as covers and fillings used in upholstered seating when subjected to a smouldering cigarette as an ignition Source.
The tests measure only the ignitability of a combination of materials used in upholstered seating and not the ignitability of a particular finished item of furniture incorporating these materials. They give an indication of, but cannot guarantee, the ignition behaviour of the finished item of furniture.
